Impedance and Far Field Characteristics of a Linear Antenna Near a Conducting Cylinder

Antennas in the proximity of complicated conducting structures such as aircraft, submarines, missiles, and satellites have, in general, analytically unpredictable impedance characteristics due to coupling effects between the antennas and these structures. As a model of the fuselage of these conducting structures, a conducting cylinder of finite length is considered and an analytic-numerical technique is used to compute the impedance characteristics of a nearby linear dipole of arbitrary length.
